2. In a rulcanizing press an upper vulcanizing chamber having a flangedbase, a hydraulic cylinder beneath the chamber and spaced a tixeddistance therefrom', said cylinder being arranged eo-axially With thechamber and having a plunger extending through the base of the latter, asupporting ring at theV top of the cylinder and separate therefrom, apair of supporting and clamping rings receiving the flanged-,base ot thechamber, and clamping and posi ti ,\ning bolts extending between andsecuredr to said rings. ,A f l 3. In a vuleanif/,ing press, thecombination of a vuleanizing chamber haring a bot` tom head; a.hydraulic chamber in alineV ment with the vulcanizing chamber; a base onwhich the hydraulic chambery and vulcanizing chamber are mounted.; a ramin the vulcanizing chamber; a piston en; tending from the ram throughthey head and base; andy asseries of posts eaeh detaehably andseparately secured to the heagdl andgbaslel and supportingtheVulcanizing chamber.
